Reini Urban used to have a module for that (Voronoi and Delauney diagrams, and geometry in general), now all I see is a README file (Geometry-0.02.readme, that is). I remember that at least the Delauney triangulation part was tied to someone else's C code. You might ask him what happened to his module or track down the C code yourself.

Update: Found it off of his hompage here.
